ールジヨイントをリンク又はアーム等の支持部材
の取付用円筒部に嵌装取付ける方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fitting a ball joint used in a link mechanism for an automobile or the like into a cylindrical part for attachment of a support member such as a link or an arm.
従来この種のボールジヨイントは、リンクやア
ーム等の支持部材に形成した円筒部内にボールジ
ヨイントのソケツトを圧入した後、該円筒部の先
端をソケツト外周面に形成した溝内にカシメ込ん
で固定する方策が採られているのが普通である。 Conventionally, this type of ball joint is manufactured by press-fitting the socket of the ball joint into a cylindrical part formed on a support member such as a link or arm, and then caulking the tip of the cylindrical part into a groove formed on the outer circumferential surface of the socket. Usually, measures are taken to fix it.

ボールジヨイントに外力が作用した場合の支持強
度が低くなつてしまうという問題を有している。 However, the support members such as the links or arms are generally press-formed products, and the cylindrical portion is usually formed by drawing with a press, so the axial length of the cylindrical portion is determined by the processing. Therefore, it is difficult to make the fitting length between the cylindrical part and the socket sufficiently long, and even though the fitting length of the cylindrical part cannot be made sufficiently long, the above-mentioned conventional method is difficult. When the tip of the cylindrical part is crimped, the actual fitting length of the cylindrical part becomes even shorter due to the crimping.
There is a problem in that the supporting strength decreases when an external force is applied to the ball joint.
本発明は上記のような従来の問題に対処するこ
とを目的とするものである。 The present invention aims to address the conventional problems as described above.

上をはかつたものである。 That is, in the present invention, when a cylindrical part is formed by drawing into a link or an arm, a corner radius part is always formed at the shoulder or root part of the cylindrical part, and the corner radius part Focusing on the fact that it has nothing to do with the fitting length, after press-fitting the cylindrical part onto the outer circumferential surface of the ball joint socket, the outer surface of the rounded corner of the cylindrical part is pressed and deformed and caulked inward. By adopting this method of fixing the cylindrical part to the socket, it is possible to securely fix the cylindrical part to the socket without reducing the effective fitting length, thereby significantly improving the mounting strength.

ツトする。 Press fit the socket 2 into the cylindrical portion 5 of the support member 4 until the end of the rounded corner 6 of the shoulder of the cylindrical portion 5 on the cylindrical side almost faces the caulking receiving recess 3 provided in the socket 2. Then, in this state, the support member 4 is placed and set on the caulking table 8 as shown in FIG.

ソケツト２の取付作業が完了する。 Then, the outer surface of the corner rounded portion 6 is caulked with a punch 9.
Press and caulk with. Then, the outer surface of the corner rounded portion 6 is crushed by the inclined surface 9' of the caulking punch 9 and deformed by being pushed inward, and the caulking protrusion 7 is fitted into the caulking receiving recess 3 and caulked, and is inserted into the socket into the cylindrical portion 5. 2 installation work is completed.
尚上記カシメは、第２図のごとく部分的に複数

めて大なるものである。 As described above, the present invention utilizes the rounded corner of the shoulder of the cylindrical part, which is unrelated to the fitting length of the cylindrical part formed on the attachment member such as the link or arm, into the socket as the caulking fixing part. Compared to the case where the tip edge of the cylindrical part is caulked, where the length of the fitting of the cylindrical part into the socket is shortened by caulking, the fitting length of the cylindrical part is lengthened and the mounting strength of the socket is greatly improved. It can be measured, and together with the ease of caulking work, it has great industrial value.
